REINFRUEMENT AND GENTERING.

To el@ whom it muy, 011mm Se it known that l, lViLLLm C. lln\\'.\.nns,Jr., a citizen of the United States. residing' et Kansas City, in thecounty ot' Jackson and State 'of Missouri, have invented certain new anduseful Improvements in Reiniliorcement and Centering, etwhichthcfollowing is s clear and accurate description, reference being hath-.tothe accompanying drawings.

My .invention relates l-o'a combined form and reinforcement useful inthe construe tion of monolithic concrete walls, tanks, silos, ,grainbinsA` etc. A

The principal advantages nttninednre; a rigid metallic structure adaptedto ect' as c forni into which wetconcrcte may be deposited and tamped,the exterior surfaces of the structure having projecting' horizontaloorrngetions which support enter plastic coatings of cement mortar andprovide means for the las verection and combination of the several inlividnal sections composing the complete structure; a very denseconcrete wall since tnmping will drive out any, air, mixed in theconcrete, through the perforated openings .in the sides of the reinlforcement; perfect reinforcement for such structures. l

Similar numerals of references designate corresponding parte in theseveral figures et the drawings. l

Figure 1. `represents s partially completed concrete tank showing theassembled sections in combination, concrete within the compartments thusformed, and outer plastered surfaces. Fig. 2. shows a view inperspeci-ive. of e sheet metal section showing the stud and side membersand the parallel horizontal corrugations reversed in positionintermediate their ends. F ig. 3. is a plan view of e single section ofexpended met-el employed in the tank construction seen in liig.v l. Fig.Lhis a side view of the section' seen in Fig. lFig. 5. is an end view ofthe section seen in Fi 8. Fign (l. represents a fragment-ary portion. ofe. sheet of'metel, slitted and ready for expansion; a single diensproduced by the expansion .of adjacent strands; and the spproximate 're'turn or these strands to their` original pesitiorr shown in the slittedsheet for the perf` Specification ef Letters Patent.

pose later described and as shown in Fig. 5. Fiozf? shows a. view inperspective of sevcrei sections, similar to the one shown in Fi 2., incombination, and concrete within the compartments thus formed. Fig. 8represents a cross sectional view taken along the linev '.v-QJ Fig. 3.Fig. 9 represents a cross sectional view taken along the line .evs Fig,3. F ig. section teken along e stud 11 in Fig. 1.

By reference to the several drawings, 11 represents e stud formed in ssheet between two side members 12 and 12. Corrugations 13 are formedlengthwise of the sheet, be ing,r reversed intermediate their ends at orin the stud so that said corrugations 13pmject outwardly beyond theplanes of the side members 12 to form outer shelves or ledges as clearlyseen in Figs. 1, 2, 4, 5 and 7. These corrugations servo to st ifen theside panels 12 materially in the combined form and reinforcement seen inFigs. 1 and 7. to support the finish cement plaster coating,r applied onthe exterior surfaces; and to unite the combined sections.

"Where sheet steel. is employed, the vcorfu-- nations are preferablyreversed intermediate theirflength 'as seen at'v14 Fig. 2. softliat whenthe sheet is bent at 20, 20, and 20", 210', and the stud 11 is therebyformed between the two side members 12and12, saidcorrurations willproject outwardly" from said stud and along the eut-cr surfaces of saidside members.

Figs. 3, 4t and 5 show a single sect-ion of expanded metal in whichthccorrugationi; 13 are 'formed on reverse sides of the sheet.

Fig, (l shows at 15 a fragmentary portion of sheet metal, slitted readyorexpansion. At 16 e single diamond formed by the expansion of adjacentstrands in 15 is shown. lt will be seen at 17 that thisdiamo'nd 'may belengthcne-.l or stretched to a 'long diamond by forces acting in thevdirection of the arrows, thus serving to contract the points 18 and 19of the diamond.:I
